Hi mcmad,
I made a post on Swiftech's H220X thread and asked about the dimensions/features of the product. It looks like you're also going to be building in an Enthoo Pro case (mine is being delivered on Friday 7/11). According to Bryan, here are the specs:
"With the reservoir the radiator is 7 cm thick. Without the reservoir it's about 2 3/4 cm thick. It's 25 cm long from the end cap to the end of the radiator. And it's 12 1/2 cm wide. There is at least 5 1/2 to 7 cm of clearance though for your RAM sticks. I hope this answers your questions."

I researched the Enthoo Pro top radiator clearance and I found watched
. Watch the video at 2:30 min. You'll see Dimitri measuring a clearance of 3 inches (76.2mm) from top of case and to the RAM slot.
The H220X will not have an included fan it seems, so add another 25mm (1 fan - push or pull) or 50mm (2 fans - push and pull). So if you wanted to do push and pull.... you need 75mm of clearance... so I think it'll fit quite snugly!!
I was afraid it wouldn't fit but after doing these calculations... I'm so excited! Any thoughts on my calculations??
